The PWS MK116 MOD2-M in .223 Wylde (brand part no. MK1-M2R-223-16) is a semi-automatic AR-platform rifle built around a 16.1-inch barrel and PWS long-stroke piston operating system, giving shooters the reduced fouling and reliability that made this PWS most popular rifle. The .223 Wylde chamber lets the rifle run both .223 Remington and 5.56 NATO ammunition interchangeably. Primary Weapons Systems pairs a 3-position adjustable gas regulator with a PicLok handguard that combines Picatinny and M-LOK mounting, and fits a Radian Raptor ambidextrous charging handle for fast manipulation from either side. Among AR-platform rifles in the AR rifles category, the MK116 favors shooters who want a piston-driven AR with genuine multi-caliber flexibility.
